Perplexity AI, the AI-powered search engine, has raised $500 million at a $15 billion valuation, tripling its value in six months. The funding reflects growing investor confidence that AI will fundamentally disrupt the $300 billion search advertising market.
Perplexity now handles 100 million queries per day, up from 10 million a year ago. The platform provides direct answers with cited sources rather than lists of links, resonating with users frustrated by ad-heavy and SEO-gamed traditional search results.
Revenue has grown to a $300 million annual run rate, primarily from Perplexity Pro subscriptions ($20/month) and a nascent advertising product that displays sponsored answers alongside organic results. Enterprise customers including Fortune 500 companies are adopting Perplexity for internal knowledge management.
Google remains the dominant search engine with 88% market share, but its share has declined for the first time in a decade. Google has responded aggressively with AI Overviews in search results, though critics say it undermines the traditional web ecosystem.
The broader AI search category also includes Microsoft's Copilot, Arc Search, and You.com. Together, these challengers represent a meaningful and growing alternative to traditional search, particularly among younger and more tech-savvy users.
